It's not callous at all, I was stunned when I first joined this forum and although there was lots of support and just knowing I wasn't alone......lots of people who I could see claimed to be healed easily in a week, and others who claimed "I am healed" only later to search for health issues most likely related to their original parasite infection being unresolved!
I had great healing when I discovered mine, only to have them return because I did not continue to fight long term. For over three years I've been posting about the benefits of raw garlic, tumeric and clove as the most basic and wonderful cleanse, with more benefits than just clearing parasites, but also healing the damage. I added a herb Centaury, and got even better results. Recently I added Lipo-C on the recomendation of another member, and my energy and health continued to improve!
So I am still learning, but also understand it's confusing and there is a mess of info/mis-info out there. Plus what works for one, may not work for everyone.
Regarding testing....this is not the only resource for parasite support, and there are countless stories of negative results when there are clearly parasites....so save your money, most of the stuff, herbs, enema supplies, even the mail order pharma's add up, cleanse anyway!
